Question

what was the day of the week 15th august 1947
​

Answer 1

Answer:

15th August 1947 has 1946 years and period from 1st January 1947 to 15th August 1947.

Now, first 1600 years have 0 days.

Next 300 years have 1 odd day.

46 years = 11 leap years + 35 non leap years = 11×2+35=57days = 1 odd day

Number of days from 1st Jan 1947 to 15th August 1947 = 227 days = 3 odd days

Hence, total number of odd days = 0+1+1+3=5

Hence, if 0 odd day it is Sunday, 1 odd day it is a Monday and so on.

Hence 5 odd days is a Friday.
